print a boot message to the serial channel. If the BOOTP process
was successful and an IP address was found, a message “BOOTP
found xxx.xxx.xxx.xxx” will be printed where xxx.xxx.xxx.xxx
is the IP address assigned by the BOOTP or DHCP server. If the BOOTP
process fails, a message indicating failure will be printed and
the serial port will be used as the debug channel.</P

echo request packets (ping). This gives a simple means to test the
health of the board.</P

should be made using a null modem cable. A gender changer may also
